Red screen when playing NTSC games

Hey! I'm new to these forums and I'm not really sure where I should post this, but this seems like the right place to me. I am having a bit of an issue. I have a PAL Wii hooked up to a PAL sdtv (it supports 60hz) and I am using an RGB cable. When I play my NTSC copy of Smash Bros Brawl off an USB loader the whole screen is red, but the image is still visible.

I tried various screen settings through the loader, but none seem to work. I have to use "FORCE NTSC" or else the screen will stay pitch black. The only way I can get the screen to work with color is when I use "FORCE PAL 50hz", but that isn't really pleasant to the eyes, at all.

Now the weird thing is is that I only have this problem with a few games. I've also got the NTSC Fortune Street, but I can get that one (and many others) to work properly by using the right settings. I remember having the Japanese Tatsunoko vs Capcom in the past and it also wouldn't work without displaying everything in red. I could just use my PAL copy of Smash, but that one doesn't support the Project M hack!

I'm pretty sure it has got something to do with the RGB cable, but I would love to know if there's a way to fix this issue. It is driving me nuts! I could just hook the Wii up the HDTV downstairs, but I'd much rather use it on a good SDTV.

It might be important to mention that I am using USB Loader GX, because it's giving me the best results when it comes to playing games in color.

For giggles, try one of the other loaders.... I'd say configurable usb mod... I've not had much occasion to go out of region for wii games; if it becomes too big of an issue might consider checking around secondhand game places & see if you can get a proper pal copy.
